IMPROVEMENT IN FEED-REGULATORS FOR LIQUIDS.

Specification forming part of Letters Patent No. 121,010, dated November 14, 1871.

To all whom it may concern:

Be it known that I, HERMANN SEYTER, of Vaihingen, in the Kingdom of Wurtemberg, have invented certain new and useful Improvements on Automatic Feed-Regulators for Liquids, of which the following is a specification:

The nature of my invention relates to improvements in the valve-gears for regulating apparatus, for the purpose of regulating the supply of liquids automatically, as will now be fully shown and described.

On the drawing, Figure 1 is a ground plan. Fig. 2 is a central longitudinal section over the line A B taken on Fig. 1. Fig. 3 is a front view of the valve-seat. Fig. 4 is a front view of the valve, and Fig. 5 is an end view of the supplyp1pe.

Similar letters refer to similar parts wherever they occur on the drawing.

a is a cistern or receiver, in which the liquid is kept and regulated. The pipe b is secured to one side of the box a by means of the nut c screwed over the projecting end of the pipe b, as shown in Fig. 2. The inner end of the pipe b is provided with a flange, b, 011 which a seat for the valve is turned. The lower end of the flange b terminates as hinges d d, through which the pin 6 is inserted. A11 arm, f, cast in one piece with the horizontal one 9, is made to swing around the hinge-pin e, as shown in Fig. 2. A float, z, is securely attached to the rear end of the arm 9, as shown. The arm g is bored out and tapped in its forward end to receive the adjustable stud h, by the turning of which the length of the arm 9 can easily be regulated. A check-nut, h, is made for the purpose of locking the stud h firmly to the arm 9 when in place. Two hooks, n a, are screwed in the upper end of the flange b, and two corresponding holes, 0 0, are made in the plate is, by which means the plate is is hung on the hooks n n, and thus made to operate easily without friction. The plate 70 is provided with guides m m m on the sides and the bottom, between which the valve or packing Zis held. Said packing projects a little above the upper end of the plate k, as shown in Fig. 2, whereby I am able to draw the packing out by means of a pair of tongs or otherwise, as required, when the packing is worn out or damaged. A third hook, p, is screwed in the flange 1) below the under side of the plate 70, by which shown, whereon the extreme end of the stud his pressing.

My feed-regulatin g apparatus is automatically operated as follows: Any liquid being forced through the supply-pipe I) would instantly open the valve k Z, provided no pressure acted on the back of said valve. As long as the box a is filled with any liquid to a height, as shown in Fig. 2, the buoyancy of the float i swings the arms fg around the fulcrum 0, whereby the eX- treme end of the piece It is pressed hard against the plate 70, thus effectually closing the opening 12, when no liquid can enter. But as soon as the liquid from the receiver a is drawn off through an opening, 1", or otherwise discharged, the weight of the arms f g and the weight of the float iswing these parts automatically around the fulcrum e, in which case the pressure of the piece h on the valve-plate k is relieved, and the liquid is now allowed to run through the pipe I). As soon as more liquid is supplied through the pipe 1) than what is discharged through the opening 1" the float is gradually lifted up by the liquid, and when of a height as shown in Fig. 2, the valve is again closed by the pressure of the stud h on the valve-plate k. The liquid may be drawn direct from the box a to the use for which it is intended, or it may be drawn into a second or larger receiver, as circumstances may require. The outer end of the pipe I) is provided with a sieve, q, Fig. 5, whereby grit and dirt are prevented from passing the valve l.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1. In combination with the float i, the arm f g with its regulating-screw h and check-nut h, movable around the hinge e, as and for the purpose set forth.

2. The combination of the valve-plate k, guides m m, valve 1, holes 0 0 with the supporting hooks n n and guidinghook p, as and for the purpose set forth. HERMAN N SEYTER.
